Studies on the pathogenesis of coeliac disease
Results of the Leucocyte Migration Inhibition (LMI) test with gluten in adult coeliac disease are shown to be affected by the histocompatibility antigen HLA-B8. Normal subjects with B8 show greater immunity than those lacking B8 and give similar results to untreated coeliacs. B8 and non-B8 coeliacs …
